Prepar3D V4.5 Notes and Compatibility Statement

With apologies for the delays (I was on a business trip in the U.S.) here are some notes on P3Dv4.5 and its compatibility with my planes.


First thing: at the moment I am writing, VRS has not yet updated Tacpack to support P3Dv4.5. Tacpack is built in such a way that it needs to be updated each time a new version of P3D is released so it is not a surprise. However, some of my planes rely heavily on it (especially the F-35 and the Typhoon) - so you may want to wait until Tacpack is updated before switching to P3Dv4.5.

That being said, on my system P3Dv4.5 works fine with no significant issues. Actually I am under the impression that frame rates and texture resolution are improved (keeping in mind that I typically fly over large photoreal sceneries such as the ones from Blue Sky).

The only minor problem I am having is a strange and subtle "blurry" effect in VR which is difficult to describe (and may be due to my system settings)… will report on that after further testing.

As I supposed, there are no buig differences in the code or compatibility in my planes - so they all work as expected. In detail:

F-35 Lightning II
Everything seems to work fine including STOVL, custom sound and fuel system. Until Tacpack is updated, DAS, TFLIR, A/A radar, loadout configurator and weapon system functionalities will not work.

Eurofighter Typhoon

Everything seems to work fine including custom sound and fuel system. Until Tacpack is updated, A/A radar, loadout configurator and weapon system functionalities will not work.

SIAI Marchetti S-211 / Aermacchi M-345

This aircraft relies on Tacpack only for the weapon system, so pretty much everything works fine.

E-2 Hawkeye / C-2 Greyhound

These aircraft rely on Tacpack only for the IFF, so pretty much everything works fine.

All freeware aircrafts will work on P3Dv4.5 to the same extent as they did in P3V4.4.
